STAI RWAY.

SPECIFICATION forming part of Letters Patent No, 367.974. dated August 9, 1887.

Application filed July 8. 1886. Serial No. 207,497, (No model.) A

T' all whom it may concern:

Be it known that I, FRANCIS O. HANSON, a citizen of the United States, and a resident of Kenton, in the county of Hardin and State of Ohio, have invented a new and useful Improvement in .Stairways, of which the followingis a specification.

My invention relates to improvements in building and supportingv stairways, in which o the ordinary stringers or supports are done away with, the braekets that hold the step and riser forming both bracket and stringer, and

.the balusters serving to lock the brackets to gether.

1 Figure 1 is a side perspective view of a piece of my stairway; Fig. 2, detached perspective views of the reverse side of my brackets; Fig. 3, a side view of railclip; Fg. 4, a top view of one bracket; Figs. 5 and 6, top and rear 2o views of the riser; Fig. 7, a top view of the tread of the step Fig. S, a rear sectional view' of clip for handrail.

A A are my brackcts; B CD, cylinder on bracket, through which bolts E F, G on end of baluster pass; H, spline or feather on side of cylindrical part C; I, lug near bottom of brackct, between which and feather H the riser fits; K L, seats in which cylindrieal parts B C fit; M M, seat on which the tread of the 0 step rests; N N, holes through which and holes P Pon the tread of the step the trend is bolted to the bracket; O, the tread of the step; Q R, bolt-holes in the tread for bolting the succeeding treads together and for tightening the 3 5 joints between the trea1d and riser; S, the riser;

T T, bolt-holes by means of which bolt U and holes Q, R, the tread, and riser are bolted together; V, overhanging head on the tread, between which and bolt U the riser is held; W, hinged or pivoted clip that connects the baluster and the hand-rail in a flexible manner, adjusting itself to any pitch of rail desired; X, pvot of the clip; Y, hand-mil.

The construction and manner of putting to 5 gether of my stairway are as follows:

In building a stairway on the side of a house, say, a series of brackets, A A, is fastened to the wall by the usual wall-supports,

each braeket being bolted by bolts E F to the succeeding bracket as the work proceeds, the brackets as they' are joined together forming a seat for the tread and riser, and also as they are bolted together forming a continuous stringer. Vhen the stringer and brackets for one side are thus formed, the braeket for. the 5 5 other end of the first or lower step is then put in place on the'othersidc; The riser is put in position between feather H and lug I. The tread O is then placed in position, the head V overhanging the riser, and the tread is 6c bolted down through holes P Q, R. Another bracket is then placed on the first bracket, the cylindrical parts B C fitting in the seats K L, when the brackets are bolted together by the bolts E F on the end of the balusters. When no balusters are used, the parts are bolted together by means of ordinary bolts having an ornamental tip that acts asa lock-nut.

Vhen the top of the stairway is reached, a bracket, A, having an extension for forming ,the landing, is attached as the last bracket, thus 'forming a perfectly sceure,simple, and neat stairway without the use of stringers.

To the top of my baluster is pivoted a clip, (shown in Fig. 8,) through which the hand- 7 rail passes. This clip, by being pivoted, allows the rail to assnme any inclination or pitch desired, the clip turning on its pvot and allowing the baluster to remain in a vertical position.v

\Vhat I claim is 1. In a. starway, the combination, with a. series of brackets, -A, each having cylindrical seats K L at the top and round parts B C at its bottom, arranged so that the rounded part 8 5 of each bracket rests in the cyli-ndrical part of the one below, of the balusters F, having their hcad-bolt extension passing through the brackets, and the nuts upon the lower end of the extensions, substantially as shown and de 0 scribed.

2. In a stairway, the combination, with the v series of brackets A, each having the rib H and lug I upon its inner side, of the risers fitting behind the lug and in front of the lug of 5 each pair of opposite brackets and the treads O, and the b0lts secnring the parts together, balusters having b01t extensions and nnts, as and for the purpose set f0rth. whereby the parts are secnred together, ns and 3. In combination with the series of brnckfor the purpose set f0rth.

ets A, each having the rb H and Ing T upon FRANCIS O. HANSON. 5 its inner side, of the risers fittng behind the Attest:

lngs and in front of the ribs of each pair of HARRY W. MERZRD,

0pp0site brackets, end the trend O, and the G. O. KEMIER.
